Missing file gives bad error message

[Christian Pearce]

>From the client I get:

cfengine:: (Can't stat /var/cfengine/inputs\cf.bigbrother)
cfengine:: Server returned error:  Host authentication failed. Did you forget 
the domain name or IP/DNS address registration (for ipv4 or ipv6)?

On the Server I get:

Apr 15 14:51:27 pearcec cfservd[25953]:  Couldn't stat filename 
/var/cfengine/inputs\cf.csc_nicstatus from host commnav-win2k.commnav.com
Apr 15 14:51:27 pearcec cfservd[25953]:  lstat
Apr 15 14:51:27 pearcec cfservd[25953]: Host authorization/authentication 
failed or access denied
Apr 15 14:51:27 pearcec cfservd[25953]: From 
(host=commnav-win2k.commnav.com,user=Administrator,ip=209.50.130.37)
Apr 15 14:51:27 pearcec cfservd[25953]:  ID from connecting host: (SYNCH 
1082055332 STAT /var/cfengine/inputs\cf.csc_nicstatus)


I was thinking this whole time I had a problem with communications, where I 
believe the problem is the file it is trying to access doesn't exist.  Which in 
this case the windows box is mangling the filename.

Is there any reason we can't put file doesn't exist?  Or is this a security 
thing?  (ie. don't give out information to a potential attacker)
